Not quite right. Analog (AMPS) runs in the same 800MHz band used by CDMA, GSM, and the old TDMA standard. This was one of the reasons the carriers wanted everyone to switch over to digital phones when they started turning on the digital networks -- more capacity (i.e., customers) without buying more spectrum. 🙂 Due to all the carrier acquisitions and inter-carrier roaming agreements, there's little distinction today between the original "cellular" 800MHz bands and the "PCS" 1900MHz bands other than from RF engineering and spectrum allocation standpoints.shamino said:Yeah, there are two GSM frequencies. One that's popular in the US and one that's popular in Europe. The good phones (so-called "tri-band") support both (old A-band analog being the third). The cheaper ones don't.
So your typical tri-band GSM phone will work on the 800, 1800, and 1900MHz bands. Unfortunately, you're not going to see the 1800MHz bands made available to US carriers any time soon; they've been used by the US military for years. There was talk a few years ago of asking the DOD to give up those bands, but then came 9/11, and that was that.
